 *     outside the range of legal Aldus-assigned tags.
 * NB: tsize_t is int32 and not uint32 because some functions
 *     return -1.
 * NB: toff_t is not off_t for many reasons; TIFFs max out at
 *     32-bit file offsets being the most important, and to ensure
 *     that it is unsigned, rather than signed.
